CLASSIFICATION TESTS FOR ORGANIC HALIDES James Anand L. Regala, Sabrina Nicolle G. Sarte, Ann Michelle Siao, Michael Sibulo, Victoria Tan Group 8 2C Pharmacy Organic Chemistry Laboratory ABSTRACT This experiment is done to classify organic halides. Most organic halides are synthetic and are not flammable. One way to classify organic halides is by classifying its ï  ¡-carbon atom as primary, secondary or tertiary. If the ï  ¡-carbon is attached to one R group, it is then primary. If the ï  ¡-carbon is attached to R groups, it is then secondary, and if attached to 3 R groups, it is then said to be tertiary. But this is only applicable if the ï  ¡-carbon is tetragonal or sp3 hybridized. Another way of classifying organic halides is by†¦show more content†¦The reactions that occur are SN2 substitutions in which iodide ion is the nucleophile; the order of reactivity is primary gt; secondary gt; tertiary. acetone RCl + NaI ------------gt; RI + NaCl acetone RBr + NaI ------------gt; RI + NaBr With the reagent, primary bromides give a precipitate of sodium bromide in about 3 min at room temperature, whereas the primary and secondary chlorides must be heated to about 500C before reaction occurs. Secondary and tertiary bromides react at 50EC, but the tertiary chlorides fail to react in a reasonable time. It should be noted that this test is necessarily limited to bromides and chlorides. [3] Methodology A. Sample tested The following are the sample tested for the classification tests for Organic Halides: a. n-butyl chloride Cl b. sec-butyl chloride Cl c. tert-butyl chloride Cl d. Chlorobenzene Cl B. Procedure A. Beilstein Test: Copper Halide Test First, a small loop was made at the end of a copper wire. The looped end was then heated directly at the oxidizing zone of a non-luminous flame. The loop was cooled and dipped into the test compound thoroughly. The loop with the test compound was then heated in a non-luminous flame. Repeat procedure with other test compounds. B. SN1: Reaction with Alcoholic AgNO3 Five drops of a test compound is added to 20 drops of 2% ethanolic AgNO3. The compound was shook and timeShow MoreRelatedClassification Tests for Carboxylic Acid and Derivatives1580 Words   |  7 PagesClassification Tests for Carboxylic Acid and Derivatives Mary Catherine Sarte, John Emmanuel Sy, Allurie Umel,Franklin Yap, Mary Christine YouIntroduction Carboxylic acids derivatives are simply groupsof compounds that contain a carbonyl group butwith an electronegative atom attached to thecarbon. The difference in the structure leads to amajor change in reactivity. The reactions of thesegroups of compounds involve nucleophilicsubstitution.

Templo, Kristinlyn Trajano, Kevin Viray, Quennie Yu Group 10, 2F-PH, Faculty of Pharmacy, University of Santo Tomas ABSTRACT The test compounds undergo different physical and chemical tests to differentiate their intrinsic physical properties and chemical properties. Physical state, color, and odor were noted through simple observation. Miscibility of the test compounds were noted through color change or a warmingRead MoreOrganic Chemistry Experiment 10 Formal Report1855 Words   |  8 PagesOrganic Chemistry Laboratory – CH 200L (2012 – 2013) 2B-Ph Group 9 Experiment 10 Identifying Carboxylic Acids and Derivatives Through Classification Tests Bianca Therese Rivera, Camille Aliana Rivera, Zarah Mae Roxas, Ma.
